Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1 to 6, a multifunctional thresher comprises a frame 3, a threshing roller 1, a screen 8, a screw 2, a winnower 7 and a separator 27.

Threshing roller 1 sets up in frame 3, threshing roller 1 both ends with frame 3 rotates and is connected, threshing roller 1 makes crops thresh through rotating. The two ends of the threshing roller 1 can be respectively provided with a bearing to realize the rotary connection with the frame 3, one end of the threshing roller 1 can be provided with a first flange 4, the first flange 4 is connected with a power device through a transmission device, the transmission device preferably selects a transmission belt, and the power device generally adopts a motor.

The screen 8 is arranged below the threshing roller 1 and is generally an arc screen; and two sides of the screen 8 are connected with the frame 3. The screen 8 of the existing equipment is welded in the frame 3, and is inconvenient to detach and replace. Therefore, this embodiment the frame 3 both sides set up respectively with the screen cloth mounting hole that screen cloth 8 is connected, screen cloth 8 both sides respectively through adjust fixed establishment 11 with the screen cloth mounting hole realizes dismantling fixed connection. Through detachable connected mode, conveniently change screen cloth 8. The adjusting and fixing mechanism 11 may be a bolt and nut fastening structure, or may be detachably connected by other connection methods.

And the distance between the threshing roller 1 and the screen 8 of the existing threshing machine is relatively fixed, so that the threshing effect is influenced because the threshing roller can not be automatically adjusted according to the feeding amount in the threshing process. For this purpose, in this embodiment, two sides of the frame 3 are respectively provided with an adjusting hole 9 connected with the screen 8, and two sides of the screen 8 are respectively connected with the adjusting hole 9 through an adjusting fixing mechanism 11; an adjusting spring 10 is arranged below the screen 8 or the adjusting and fixing mechanism 11. The mounting height of the screen 8 can be adjusted by the adjusting holes 9 and the adjusting springs 10, and the vibration of the screen 8 during threshing is reduced.

As a specific installation mode of the adjusting spring 10, the adjusting spring 10 can be respectively arranged at two sides below the screen 8. And the adjusting spring 10 may be located outside the frame 3.

For better implementation of the above structure, as shown in fig. 4, the screen 8 may be provided with an ear 12 connected to the adjusting and fixing mechanism 11. The adjusting and fixing mechanism 11 may include a screw, and a through hole connected to the screw is provided on the ear 12. Namely, the screw or bolt is fixed by a nut or other means after passing through the through hole on the ear part 12 and the frame 3.

The above form of the adjusting hole 9 may be a strip-shaped adjusting hole or the like.

The spiral propeller 2 is arranged in the frame 3 below the screen mesh 8 and can rotate, the spiral propeller 2 is generally positioned at the bottom of the frame 3, and the spiral propeller 2 propels the threshed crop fruits by rotating. One end of the screw propeller 2 is provided with a second flange 6, and the second flange 6 is connected with another power device through a transmission belt. The drive belt of the present embodiment may be replaced with other drive means.

In the above mode, the threshing roller 1 and the spiral propeller 2 are respectively driven by one power device, so that the defect of insufficient power caused by the fact that the threshing roller 1 and the spiral propeller 2 are simultaneously driven by one motor in the existing equipment is overcome. The power of the thresher is more sufficient, the operation is more stable, and the threshing efficiency is improved.

A feed inlet 28 for allowing crops to be threshed to enter is formed in one side above the rack 3, a discharge outlet 29 for discharging coarse straws after threshing is formed in the other side of the rack 3, and a baffle 30 is arranged above the discharge outlet 29. The coarse material discharged from the discharge port 29 is thrown upward to a certain height, which affects the working environment. Therefore, the range of the coarse material to be thrown out is reduced by the baffle 30, and the working environment is better. And one side of the baffle 30 can be rotatably connected with the frame 3 for adjusting the baffle 30. Furthermore, an adjusting hole 31 for adjusting the rotation radian of the baffle 30 is formed in the baffle 30, and an adjusting screw 32 is arranged in the adjusting hole 31. That is, the baffle 30 is rotated to change the inclination degree, the adjusting screw 32 moves in the adjusting hole 31, and after adjustment, the adjusting screw 32 at a certain position in the adjusting hole 31 can be fixed by a nut.

The shape of the adjustment hole 31 may preferably be an arc shape as shown in fig. 1 and 2, and may have other shapes.

The other end of the screw propeller 2 can be connected with the winnower 7; the winnower 7 is connected with the separator 27 through a material pipe 26. A cone can be arranged in the separator 27, after the threshed grains fall on the cone, grains are separated from fine materials, and the lower end of the separator 27 is a grain outlet.

And as shown in fig. 3, in order to adjust the air volume in the separator 27, an adjusting valve 33 is arranged on the material pipe 26, and the air volume is adjusted by adjusting the closing degree of the adjusting valve 33.

As shown in fig. 5, the grain thrower 7 comprises a grain thrower housing 18 and a blade mechanism not shown arranged inside said grain thrower housing 18; the blade mechanism is connected with the spiral propeller 2; the winnower shell 18 is divided into an upper winnower shell 19 and a lower winnower shell 20 which are independent from each other; one side of the upper winnower shell 19 and one side of the lower winnower shell 20 are connected in a rotatable mode, and the other side of the upper winnower shell 19 and the other side of the lower winnower shell 20 are connected in a detachable mode. The existing winnower shell 18 is of an integral structure, and through the arrangement mode, the blade mechanism in the winnower 7 is convenient to install, replace and maintain.

The interface of the upper and

lower winnower shells

19, 20 coincides with the axis of the shaft of the blade mechanism. The winnower shell 18 can be divided into two parts according to the plane of the axis of the rotating shaft of the blade mechanism. The upper winnower housing 19 and the lower winnower housing 20 are hinged at one side, namely, the upper winnower housing and the lower winnower housing are rotatably connected in a hinged mode. For example, the upper grain elevator housing 19 and the lower grain elevator housing 20 are connected at one side by a hinge 21.
